SHUTTLE.

To all whom it may concern:

Be it known that I, Ensues H. DAUDELIN, a citizen of the United States, residing at Fall River, county of Bristol, Commonwealth of Massachusetts, have invented cer tain new and useful Improvements in Shuttles, of which the following is a specification.

The subject matter of my present invention is an improvement in 1.00m shuttles of the so-called self-threading or hand threading type in which the thread is drawn through a tortuous passage into the eye of the shuttle. My invention relates more particularly to the guarding of the end of the shuttle eye although the principles involved are somewhat varied in application.

As is well known in this type of shuttle it is of great importance that the eye be so guarded as to effectively prevent any escape of the thread from its confines while permitting a ready entrance of the thread into the eye passage and a free run therethrough.

The construction and operation of my present invention will be more fully described in the specification which follows, and as illustrative thereof I have shown in the drawings an embodiment well adapted for commercial production and practical use. Throughout the specification and drawings like reference numerals are employed to indicate corresponding parts, and in the drawmes:

Figure 1 is a plan view of the thread delivery end of the shuttle.

Fig. 2 is a side view of the same showing the thread approaching the guide eye.

Fig. 3 is a similar view showing the thread about to enter the eye.

Fig. 4 is a like view showing the thread lodged in the eye, and

Fig. 5 is a section on the broken line inclicated at 5-5 Figs. 1 and 2.

I have indicated at 1 a shuttle body having the usual bobbin cavity 2 and threading eye 3 to which threading slots indicated at 4 and 5 lead. The slots 4 and 5 constitute a continuous passage from the bobbin chamber 2 into the eye 3. The eye 3 is suitably guarded by glass posts 6 which constitute anti friction guides for the thread but which form no part of my present invention. At the outer end of the eye 3 is an extended recess 7 extending somewhat to each side of the eye passage and at its forward end Specification of Letters Patent.

Application filed December 18, 1917. Serial No. 207,753.

7 extending somewhat upwardly to meet the rearward passage 5.

To the rear of this upward extension 7 and toward the eye slightly above its plane is a raised shouldenor projection 8 which terminates abruptly in the downward pas.- sage 9 which enters the eye in the vertical plane. This shoulder is slightly rounded on its forward end so that the thread at T will lead up over it, although deflected by the guard 10.

The guard 10 is a small runner shaped staple driven in the recess 7 and lodged in the shuttle body 1 above said recess. It is disposed with its runner shaped end 10 in the recess extension 7 so as to inclose the projection shoulder 8, which preferably extends slightly beyond the vertical plane of the staple 10.

As the thread is drawn into the eye as at T, T and T in Fig. 1 and as is shown in side views in Figs. 2, 3 and 4, it meets in its passage through the horizontal slot 5 the runner shaped end 10* of the staple 10 being deflected thereby or bent. As the thread T passes further through the slot 5 on its way to the vertical slot 9 it draws over the runner end of the staple 10 until finally it is drawn into the eye 3 through which it is to travel. Any escape of the thread is efiectuallv barred not only by the staple 10 but by the shoulder 8 and such escape is thereby most efficiently prevented.

Various modification may obviously be made in the details of the structure, all without departing from the spirit of my invention if within the limits of the appended claims.

What I therefore claim and desire to secure by Letters Patent is:

1. In a hand threading shuttle having a bobbin chamber, a threading eye, and a threading slot connecting said chamber and eye, a guard disposed horizontally across the outer end of said eye and having a forwardly and upwardly inclined runnershaped end disposed across said threading slot relatively considerably in advance of the intersection of said slot with the threading eye whereby. in the threading operation the leading portion of the thread is deflected downwardly and behind said guard while the following portion of the thread is guided along said slot and is laid from above into the eye, and a projection on the shuttle body between the eye and slot and projecting outwardly beyond the plane of said eye guard and along which the following portion of the thread travels into the eye when deflected by said runner-shaped end of the guard.

2. In a hand threading shuttle having a bobbin chamber, a guarded threading eye, and a threading slot starting from said chamber and terminating above the plane of the eye at the outer end thereof and there being intersected by a transverse cut providing a thread passage connecting said eye and slot said out leaving a horizontally disposed shoulder disposed beyond the vertical plane of the eye guard, an eye guard disposed at the outer end of the eye and having a forwardly and upwardly inclined runnershaped end inclosing said shoulder and interseeting said threading slot considerably in advance of the juncture of said slot and eye whereby in the threading operation the leading portion of the thread is deflected downwardly and behind the guard while the following portion of the thread is guided along the shoulder included by said guard and is laid into the eye from above.

In testimony whereof I aflix my signature in presence of two witnesses.
